What is the reason for doing a test cross? a. to identify heterozygous individuals with the dominant phenotype b. to determine which allele is dominant and which is recessive c. to identify homozygous recessive individuals in the F2 d. to determine if two genes assort independently
Independent assortment means thata. two genes tend to be inherited together.b. which allele of a gene is included in a gamete has noeffect on which allele of a second gene is included in thesame gamete.c. which allele of a gene is included in a gametedetermines which allele of a second gene is included inthe same gamete.d. homologous chromosomes do not separate during meiosis.
Which among the following statements is INCORRECT? O A. The arrangement of chromosomes in metaphase I and metaphase Il in Meiosis is not random, therefore, the inheritance of a trait will not affect the inheritance of the other trait O B. All statements are correct OCif a cross produces 100% heterozygous genotype, then all of the offspring will exhibit the dominant allele D.Only one of the two gene copies present in an organism is distributed to each gamete (egg cell / sperm cell) because of the separation of homologous chromosomes and sister chromatids during meiosis.

Inthe F2 generation of a monohybrid cross that begins when adominant homozygote is crossed with a recessive homozygote,you would expecta. three plants with yellow seeds to every plant with greenseeds.b. plants with one yellow seed for every green seed.c. only plants with the genotype Yy.d. only plants that produce yellow seeds.e.

Manx cats have no tail. This is caused by a dominantmutation M, which is embryo lethal when homozygous. An unlinked gene B controls the color of the fur onthe cat's tail. The dominant B allele produces black fur on tails, while the recessive allele b produceswhite fur on tails. A Manx cat that is B/B is crossed to a white-tailed cat. Half of the F1 progeny hadthe Manx phenotype and the other half had normal, black tails.The F1 cats with the Manx phenotype were crossed to each other, producing F2 cats. What is the ratioof the following phenotypes in the F2
